Hi, not long ago a purchased a couple of pit bikes that were non-runners for the purpose of fixing up and having some fun. Progress has been pretty smooth thus far with parts being relatively easy to find and cheap, however, I'm having a little trouble with one bike.

I'm having difficulty identifying the make of one of the bikes engines. Now, admittedly I should have done my homework first and tried to identify the engine first in order to find replacement parts sould I need them...but I got a little excited and decided to just get on with trying to fix it.

The third gear is effectively non-existent so I wanted to take it apart to replace the gear cluster. However, after I had removed the engine from the frame I found that the lower engine mount on the right hand crankcase had cracked off....nice.

Then as I started to disassemble the engine I found that someone has previously tried and failed to disassemble this engine before, as the flywheel locking nut was missing and the thread on the crankshaft was mushroomed flat.....great.

So now I need a replacement right hand crankcase, crank shaft and gear cluster.......lovely.

Now the problem. I have no idea what make the engine is, and obviously I don't want to buy parts online that may or may not fit.

The engine size I'm told is a 110cc and the number on the engine is FY152FMH, which I think (after a lot of looking online) is either a lifan or a gongyu....the head on it is def gongyu.

I guess another question should be, is worth the effort in fixing or should I just buy another engine?

So, could someone be kind enough to confirm this for me/ point me in the right direction for replacement parts please?

Also does anyone have/know where I can find a loom wiring diagram for a 110cc pit bike with a 5 wire stator + electric start + key ignition/switch?

Many thanks

The engine number is coming up as a Lifan.

If the thread on the crank is mushroomed bad, then it'll probably need replacing.

With the problems it has, (3rd, casing, crank) it's not really worth re building, plus the cost of gaskets and whatever you might find wrong in there.

Just keep what you can for spares and buy another, you should be able to pick one up cheap.

Cheers guys, I looked for replacement parts and the total cost was getting pretty close to the cost of a new engine anyway. So yeh, new engine it is.

Is Lifan a crap make or something as the parts aren't that easy to find, i couldn't find any new crank cases for sell anywhere except in Australia, and that was expensive?

p.s can anyone help me with the wiring loom?

thanks
